CIR-21

3M's CIR-21 represents the next evolution in Terminals - Wire Splice Connectors technology, optimized for 5G infrastructure and telecom applications. This precision-engineered solution addresses the growing demand for high-speed data transmission with minimal insertion loss across its operating range.The Butt Splice, Inline, Individual Openings architecture enables parallel wire management in space-constrained installations. When deployed in base station equipment, its low-profile design reduces cabinet footprint by up to 25% compared to conventional solutions.Configured with 2 access ports, this terminal facilitates rapid field servicing without compromising connection integrity. Network technicians benefit from its tool-less reconfiguration capabilities.Utilizing Crimp technology, the connector maintains stable contact resistance below 5m throughout its service life. This exceeds TIA-968-B requirements for central office equipment.Compatible with 1/0-1 AWG conductors, the 590DC-CDG supports hybrid fiber-copper networks. Its broad compatibility range simplifies inventory management for telecom operators.The Non-Insulated system incorporates halogen-free materials meeting IEC 60754-1 standards. This makes the connector suitable for plenum-rated installations where smoke emission is a concern.
